5. a) A scientist measures the rat population in an ecosystem. The population follows a logistical growth curve. When the rat population reaches 2,000, the rats begin to compete with each other for resources.
They reach a carrying capacity of 5,000. Draw the growth curve for the rats on the graph below. Label the
point where they begin competing and where they reach carrying capacity. (6 points)
